2. Insert the air intake into the 4” (10.2cm) diameter hole and fasten to the
floor with the screws provided.
3. Adjust the air intake so the lower tube extends below the underside
sheathing and secure with the screws provided. THE BOTTOM OF THE

4. Seal the openings around the air intake and underside sheathing to resist
the entrance of rodents.
5. Position the water heater so it is centered above the air intake. (Note:
The water heater should also be centered with the openings in the

Venting
Make certain the flue baffle is in place and centered in flue tube. Cut a 7 1/4
inch (18.5cm) diameter hole in the ceiling and roof directly above the flue of the
water heater. Center the water heater beneath the 7 1/4 (18.5cm) inch
diameter holes in the roof and ceiling for proper alignment of the flue tube and
roof jack vent. Apply non-hardening mastic on the roof, around the previously
cut hole, to form a weather seal with the flashing of the gas vent roof jack
assembly. Note: Only the roof jacks listed in Figure 2 can be used on this
water heater. Insert the 3” (7.62 cm) vent connector extension (shipped
telescoped) into the gas vent roof jack assembly and down onto the flue pipe
extruding from the top of the water heater. Fasten the 3” (7.62 cm) vent
connector to the flue pipe using the 3” (7.62 cm) clamp provided. After all
connections are made, apply a bead of silicone (supplied with vent kit) to all
vent seams and connections above the flue pipe (some kits may contain
silicone bands to seal vent joints).
